Effect Of Exercise

Question 1

What happens when your muscles contract

Answer 1

You need more respiration to take place

i.e more o2 and glucose, quicker co2 release

Question 2

What does exercise do

Answer 2

Causes increased heart/breathing rate

Question 3

What happens when arteries dilate

Answer 3

More blood to muscles which increase oxygen/glucose supply, so co2 is removed quicker

Question 4

What are your everyday muscle movements made possible by?

Answer 4

AEROBIC respiration

Question 5

If the heart rate is increased what happens

Answer 5

The blood can’t supply O2 quick enough

Question 6

What is different about ANAEROBIC respiration

Answer 6

It doesn’t involve much oxygen and is less efficient

Converts glucose into lactic acid and energy

Question 7

What is oxygen debt

Answer 7

Lactic acid needs to be got rid of, so it reacts with O2 to form co2 and water

Question 8

What is energy from respiration use to do?

Answer 8

Make muscles contract
